Multivariate analysis was conducted for assessment of taxonomic relationships of 141 persimmon (Diospyros kaki Thunb.) cultivars that consisted of 110 Korean native and 31 Japanese cultivars. As result of principal component (PC) analysis using 78 variables from 141 cultivars, eigen value of the first principal component was 6.7 and the first two PCs was accountable for 15.6% of the total variance. Variables highly correlated with PC 1 were those related to fruit astringency. Pollination constant non-astringent (PCNA), pollination variant non-astringent (PVNA) and pollination variant astringent (PVA) were distributed in the positive region of PC 1 axis. Variables highly correlated with PC 2 were those related to fruit shape. Cultivars with depressed ovate fruit shape were distributed in the positive region of PC 2; those with triangular fruit shape in the negative region of PC 2. Cultivars could be classified into 11 groups on the basis of cluster analysis. By Wards minmum variance cluster analysis, cultivars were divided into two groups; first group included cultivars of pollination constant astringent (PCA) type and second included those of non-PCA type. However, by complete linkage cluster analysis, cultivars were divided into two groups; first group included cultivars of triangular fruit shape and second included those of non-trianglar fruit shape. Because average linkage and single linkage cluster analysis are biased toward producing clusters with small variance, any cultivars were not formed cluster, especially in case of single linkage cluster analysis.
